I have carried out a series of searches on Google on the subject of Mason or potter wasps, but there is limited information, the questions I need answering are as follows
1# How many eggs are laid in each cell, as I have only been lucky enough to observe the adult placing one caterpillar in the cell, but the cells are quite large, so there may be more than one egg.
2# How long before the eggs hatch and the young leave the cell, the only information suggests when the eggs hatch the food store only lasts around twelve days.
3# How do the adults & young spend the winter, do they hibernate and if so together or on their own.
Hopefully I will be able to answer some of these questions next year.
